IBM Software
© 2009 IBM Corporation13 IBM z/VM Management Software
Product Overview
� Manage tapes
• Define tapes in a catalog, including:
• Free or used
• Retention/expiration information
• ATL/VTS or manual mount
• Data Security Erase
• Group tapes together into pools
• Ownership and access control
• Media type
� Manage devices
• Define available devices
• Dedicated or assignable
• Group devices together into device pools
• ATL/VTS or manual mount• Any other grouping you choose
(read only vs. write, location, etc.)
• Share devices with other systems
� Manage mount requests
– Volume specific and scratch requests
• Standard Label
• Non-Label
• Bypass Label Processing
IBM Software

Key Benefits
� Effective management of tapes in ATL or VTS
– Granular access control
– Expiration processing
– Notification for low threshold for tape resources
– Interacts with devices through DFSMSRMS on z/VM
� Improved accuracy of manual tape processing
– Granular access control
– Automated interface to Operator for manual mounts
– Internal label verification at attach/give and detach (SL only)
– Read/Write verification at attach/give
� Integrated management of z/OS and z/VM tapes using DFSMSrmm on z/OS
– Optionally use RMM on z/OS as the tape catalog for z/VM and z/OS tapes
– Tapes, access control, and retention managed by the existing RMM catalog
– Accessible via Tape Manager on z/VM
– Tapes managed by RMM
– Devices managed by Tape Manager

Tape Manager
Operator Console on z/VM:
MOUNT VOLSER 123456 …
Manual
Option 1:
Tape Manager finds a
specific volser available
as scratch in the catalog
Operator must mount the specific volser
Scratch Mount Requests in Standard Mode
Option 2:
Tape Manager asks
Operator to mount any
available scratch tape
Operator Console on z/VM:
MOUNT SCRATCH …
� Operator can mount any available scratch tape
� Tape must be in the catalog as scratch
� Tape must be in requesting mount pool or free pool
DFSMSRMS
ATL/VTS
Tape Manager finds a
specific volser available as
scratch in the catalog
Specific volser requested and mounted
Option 1 vs. Option 2 controlled by

Data Security Erase (DSE)
� Erase (sensitive) data before tape is reused
� Option to enable DSE at tape pool or individual tape level
– DSE-enabled flag included in each catalog entry
� DSE-enabled tapes marked as DSE-ready when freed
� Tape Manager DSE utility (TMDSE) executed on a separate user ID
– Started manually or automatically with Operations Manager
– Queries the catalog to find all tapes with DSE-ready flag on
– Mounts each tape
• Verifies volume label if possible– Configuration option to perform DSE on NL tapes or not
• Erases tape
• Turns off DSE-ready flag in catalog
– Tape is now available for scratch unless its HOLD flag is on
